Gyllenhaal plays a strung-out history professor called Adam Bell, who encounters an identical man named Anthony St. Claire (also Gyllenhaal) bearing a sinister threat. Mélanie Laurent, Isabella Rossellini and Sarah Gadon join him in his hellish struggle for survival in academe.

Aiming to be a notch above your average EPK gush-fest, this featurette explores the themes of the film, charting Adam’s struggles with his inner demons and demonstrates how they went about making sure the shots featuring both Gyllenhaals lined up. Spoiler alert: it involved a tennis ball on a stand.

The film, loosely adapted from José Saramago’s book by Javier Gullon, promises dramatic thrills with a metaphysical flavour. The trailer arrived earlier this month and you can see it here. American audiences will see it on March 14 and while there is no date set yet, we should get Enemy in the first half of this year.
